The Senate was the most powerful branch of the Roman republic, and senators held the position for life. The executive branch was made up of two consuls, elected yearly. These two consuls had almost kingly powers, and each could veto, or disapprove of the other's decision.
Biodiversity is the variety of life in a habitat or ecosystem. It is important because without it the food chain would most likely collapse.
The correct answer is - mass extinction.
The most dramatic extinction of large prehistoric mammals occurred when the ice age was ending. The climate suddenly changed dramatically, thus the environment changed very quickly in response. Also, there's indications that maybe a meteorite hit Greenland and caused dramatic changes in just few hours and days. The larger mammals were all very specialized animals, so even small changes in the environment are fatal for them, as seen in this case.
It is interesting though that only the megafauna died out, while the medium sized and smaller animals survived, largely because they are not very specialized but are much more opportunistic in their food choices. Some of the large mammals that died out in this period are the smilodon, homotherium, american lion, short-faced bear, mastodon, mammoth, American horses, American camels, giant sloth etc.

Lysine (positively charged amino acid)
<u>It is present on the outside of a globular protien.</u>
Explanation:
<u>Formula of lysine:</u>
C6H14N2O2
Globular proteins are folded such that their tertiary structure consists of the polar, or hydrophilic, amino acids arranged on the outside and the nonpolar, or hydrophobic, amino acids on the inside of the three-dimensional shape. This arrangement is responsible for the solubility of globular proteins in water.
<u>As lysine is a positively charged polar / hydrophilic amino acid , it is arranged on the outside of the globular protien.</u>
